Andrew Lee Hall Sr., 46, of Des Moines, was fatally wounded after being shot outside the Maingate Bar and Grill on East Grand Avenue near the Iowa State Fairgrounds on December 2, 2021. Police say the violence began when 17-year-old Drake Russell Armstrong became involved in an argument with a woman in the bar’s parking lot; Hall intervened to break up the confrontation and was shot in the abdomen. He was treated in hospital for more than three weeks and died in late December 2021, with accounts placing his death on December 26 or 27.

Later filings connected with a civil lawsuit say Hall had gone to the Maingate with his teenage son and that Armstrong was sitting in the passenger seat of the son’s vehicle before getting out and shooting Hall. The son told investigators he was less than five feet away when the shooting occurred. Police arrested Armstrong; initial charges included attempted murder and related counts, and prosecutors later charged first-degree murder after Hall’s death. The case also involved bartender Jessica Olson, who faced charges for serving alcohol to a minor and acting as an accessory after the fact and later pleaded guilty and received probation. Hall left behind a wife, children and grandchildren.

Anyone who knew Andrew Hall or who has information about the events outside the Maingate on December 2, 2021, is asked to come forward.
